surreality/src/linear_algebra.rs, branch main A game and rendering engine written in Rust. There are many like it, but this one is ours. http://code.irenes.space/surreality/atom?h=main 2026-07-18T10:48:13+00:00 pull the shader data stuff into its own file 2026-07-18T10:48:13+00:00 Irene Knapp ireneista@irenes.space 2026-07-18T10:48:13+00:00 urn:sha1:0371c8f086008d604dddfe92d021f8ecfe398436 separate from the linear algebra stuff Force-Push: yes Change-Id: I26fc7ac596f304fa35ca7a4d0e1349d4fa0685ee draw the image 2026-07-18T10:15:56+00:00 Irene Knapp ireneista@irenes.space 2026-07-18T10:15:56+00:00 urn:sha1:40bd889e67d6f9fb4ce837fcda4ddf5a34c54b47 wow yay :) Force-Push: yes Change-Id: I7053ec3a7ed7b46e9c9d1260fd0f73b398b798af load a texture image 2026-07-18T08:14:49+00:00 Irene Knapp ireneista@irenes.space 2026-07-18T01:43:05+00:00 urn:sha1:f70917c8aae0d184ed7ce5e63e6347fdc21921e3 also refactor buffer management a little this doesn't yet draw the texture Change-Id: Id2efa761223a588bf599041ac525c3b988f0113b Force-Push: yes add Transformation::look_at() 2026-07-17T21:25:30+00:00 Irene Knapp ireneista@irenes.space 2026-07-17T21:25:30+00:00 urn:sha1:f7e6dec079dcbbc26a9e047cf2b0acf23c091836 now we have real camera behavior. yay! Force-Push: yes Change-Id: I291d0cce0f2624e9bff8356c8dbe2aabc49599e2 it spins!!!! 2026-07-16T05:35:16+00:00 Irene Knapp ireneista@irenes.space 2026-07-13T20:25:16+00:00 urn:sha1:5dddb64f6a2fd072f2a26d4400f9a2a84386dc4e ahem. more formally: provide animated uniforms to the shader, and use them the tutorial just wants us to do three matrices, and to defer all the actual math to a library it recommends. that would certainly be simpler. anyway, we use quaterion+offset for everything but the projection frustum, and do all the math ourselves Change-Id: I399f432bebb1e7ca4d4342efa1d5aaf37b32f427 Force-Push: yes use an index buffer now, and draw two triangles 2026-07-12T01:00:08+00:00 Irene Knapp ireneista@irenes.space 2026-07-12T01:00:08+00:00 urn:sha1:429dbcb9e0fcbb0b1c800f928cccc3b06800e6a4 Force-Push: yes Change-Id: I2c58bad402908fa36caf271da3cae78e43ef3110 allocate and use a vertex buffer 2026-07-10T04:26:44+00:00 Irene Knapp ireneista@irenes.space 2026-07-10T04:26:44+00:00 urn:sha1:cd3b77fea9307d9c15718a9e5e17035f7e71ac25 kinda cool how the driver interfaces with the kernel to map memory on our behalf Force-Push: yes Change-Id: I906f68b59dcedc1fd6d9bfc52c9b299abc9cd828
